“It feels amazing!” says Tuscany, a pro free skier who suffered a career-ending injury in 2006 when he overshot a jump and broke his back. “So blessed to have the world record for the most high-fives, I think we are the deserving champions for sure.”

His challenge, which he kicked off at Fort Mason, took him 23 hours and all around the city, from AT&T Park to the Horseshoe Bar to a bus stop. So, what’s the reigning world champ plan to do next?

“Just keep spreading the name and mission of High Fives to everybody that I high-five.”
